Durable Prefabricated Steel Structure Warehouse with High Load-Bearing Capacity and Quick Installation

Industrial Prefabricated Steel Structure Buildings — Warehouse, Workshop, Factory. We design, fabricate and erect industrial steel structure buildings including warehouses, workshops, factories and garages, available in single-storey or multi-storey configurations. The complete package includes welded H-section steel frames, purlins, bracing, and roof/wall panels. Design services are provided free of charge, and we can dispatch construction teams as required.

Main frame construction utilizes welded H-section steel. We work with the following steel grades according to project standards:

• Chinese Standards: Q235, Q355
• American Standards: A36, A572 Grade 50, A992
• European Standards: S235JR, S355JR, S460NL

A992 is the preferred American structural steel for building frames, while S460NL represents European high-strength fine-grain steel suitable for heavily loaded structural members. Simply specify the required grade from your drawings, and we will source and fabricate accordingly.

Main Frame & Secondary Steel:

• Columns and Beams: Welded H-section steel with straight or tapered cross-sections
• Purlins: C and Z sections manufactured from Q235, A36, or S235JR steel
• Bracing Systems: V-shaped angle steel braces, steel tube tie rods, and round bar braces
• Vertical/Horizontal Bracing: Angle steel, round bar, or steel tube configurations

Roof and Wall Systems:

• Roof Panels: EPS, glass fiber, rock wool, or PU sandwich panels
• Wall Panels: Sandwich panels or corrugated steel sheets
• Windows: Aluminum alloy, PVC, or sandwich panel windows
• Doors: Sliding sandwich panel doors, rolling metal doors, or personnel doors
• Drainage: Galvanized gutters with PVC downpipes
• Accessories: Ventilation fans, skylight panels, sealants, and fastening systems

Connecting plates, base plates, and stiffeners are precision-cut from plate materials conforming to project standards — including JIS G3103 (Japanese standard, with common sizes such as 28 * 2000 * L), or equivalent ASTM and EN specifications. All plates are cut and drilled according to drawing specifications and packaged with the main frame to ensure no separation during transit.

Complimentary design services include layout drawings, elevations, foundation plans, and material lists based on your site data. For construction, we provide experienced teams with international project experience including high-rise structures, stadiums, and industrial plants. For self-build projects, we supply comprehensive drawings, assembly sequences, and ongoing technical support.

To provide an accurate quotation, we require the following information:

1. Building purpose — warehouse, workshop, factory, garage
2. Dimensions — length * width * eave height, and number of storeys
3. Environmental loads — wind speed, snow load, seismic zone classification
4. Steel standard and grade — GB, ASTM (A992/A572) or EN (S355JR/S460NL)
5. Roof and wall specifications — panel type and thickness, or corrugated sheet
6. Door, window, fan, and skylight requirements
7. Erection preference — whether you require our construction services

Our engineering team will then produce detailed drawings and provide a comprehensive quotation.

Frames are shipped on steel pallets within containers; panels are film-wrapped for protection; all fixings, plates, and bolts are boxed and inventoried. Standard lead time is 30 days following deposit receipt, subject to order quantity and complexity.
